WebFirst, a numpy array of 4 elements is constructed with the real component w=0 for both the vector to be rotated vector and the rotation axis rot_axis. The axis angle … WebMar 6, 2016 · Now you can find out the angle of rotation and axis of rotation from the rotation matrix itself (i.e. in your case only "Q" matrix is enough). The rotation angle is given by following formula: rotation_angle = acos(0.5*trace(Q)); I carried out above steps on the example provided by you and got the correct result. I am attaching the script for ...
